I don't know that this kind of thing would make me run out and get yet another edition of one of the plays -- but if I was in the market for one and I saw half a dozen different volumes to choose from? Something like this might stand out! (Of course, this does not get into the discussion of which volumes have the best glossary, footnotes, edits and so on...we're talking entirely about judging a book by its cover, here. But let's be real, plenty of people do that.)
